The correlations I see between this issue and climate are in the seriousness of risk, timescale, and effort needed to respond to the problem. Overall Cascadia may have an even greater problem with the quake and tsunami than they/we have with climate change - the long tail of risk includes immediate catastrophe as a possibility. If they/we are lucky for the next 50 years, taking action on both mitigating emissions and tsunami-proofing our coastal areas without a catastrophe hitting, my guess is the cost of tsunami-proofing in the region would be higher than mitigating and adapting to climate change.

One other overlap is that one way to adapt to tsunamis is to relocate away from sea level, at least with your most vulnerable communities and critical infrastructure, and that will help with sea level rise as well. Finally, they are doing something to deal with this problem, just not doing enough.

Having said all that, one thing that did bother me with the article is that some things seemed exaggerated. Getting knocked over by ankle-deep running water? Call me skeptical. Same thing with Sacramento's alleged vulnerability to tsunamis - I'd like to get learn more about this, but I do know that there are two constriction points between the city and the ocean (Golden Gate and Carquinez Strait) and lots of room for water to spread. Hopefully the other risks aren't exaggerated.
